A new fingerprint analysis method will make it easier for forensic investigators to study old, dry fingerprints, potentially unmasking new evidence in cold cases. Using gold nanoparticles, researchers were able to target amino acids on non-porous surfaces, which will allow better analysis of latent fingerprints.
Dutch scientists have come up with a DNA test that can determine a person's natural hair color, using no more than a drop of blood or saliva. They say their method can predict hair color with up to 90 percent accuracy, helping forensic investigators identify an unknown person's characteristics.
